  • Serviceability assessment and sensitivity analysis of cast iron water pipes under time-dependent deterioration using stochastic approaches

    Determination of the depth of the corrosion pit is essential to predict the serviceability of corrosion affected pipes and to instigate maintenance and repairs for the pipeline system. In this paper, a reliability-based methodology for serviceability assessment of corrosion affected pipes is presented. The depth of corrosion pit is considered as the critical parameter that causes ...

  • Expect The Unexpected During Inline Inspection Runs

    Over the past decade, several high profile oil and gas pipeline failures have shown that the consequences of a rupture can be extremely severe for both the environment and human life, and can result in billions of dollars in remediation costs. Because of all these negative consequences, governments have made it mandatory to conduct routine inspections on these assets to prevent catastrophic ...

  • Integrity management: how direct assessment is improving pipeline inspection

    Oil and gas pipelines have been around for well over a century, and some of the earliest constructed are still in service today.  Although early pipelines were made of wood, and in the past few decades plastics and composite materials have increased in popularity, the vast majority of pipelines in service today are constructed with steel.  Like any pipe material, steel pipe has its ...

  • An Overview of STI Group’s Services for the Oil & Gas Production Sector

    Oil and gas production companies often operate on a tight margin, making both the price of oil and the costs of extraction and transport extremely important. While of course there is little companies can do to affect the price of oil, it is imperative that they get the best prices and quality possible when it comes to equipment, fabrication, and services. STI Group provides the quality, safety, ...

  • Reducing costs through precise remote tracking

    Historically, inline inspection (ILI) tools used to identify defects on oil and gas pipelines have been tracked by field teams. However, recent technology advancements now allow pipeline owners to track pigs remotely, which is a much safer and cheaper alternative to traditional tracking. As pipeline integrity technology advances, asset owners are now using a wide variety of tools to detect ...

  • 3 Things Overheard at the 2016 Petroleum Safety Conference

    Last week, the ENFORM Petroleum Safety Conference (PSC) brought oil and gas safety professionals together once again to connect with each other in beautiful Banff.

  • Collecting Data from the Field? Follow this Formula for Success!

    A drill operator at an oil rig is looking tired and “out of it.” He’s yawning, his movements are slow, and he doesn’t appear to be paying much attention to detail. Immediately, the supervisor relieves the drill operator of his duties and reassigns the task. He quickly enters the work observation in his iPad. His device has an offline mode that will sync up with his ...

  • Questions and answers about oil and gas wastewater spills

    Nearly 3 million gallons of briny water generated by crude oil production has leaked from a North Dakota pipeline and reached two creeks, making it the biggest spill of this type of wastewater since the state's Bakken formation oil boom began in 2006. Here are some questions and answers about oil and gas saltwater spills: Q: What does this liquid consist of, and where does it come from? A: ...

  • The stifled expertise of safety communications

    Safety communications can offer an important contribution to workplace safety. In the oil and gas industry, however, safety communications have received very little dedicated attention. There is a wide gap between how safety communications are practised in this industry and extensive research on what communication means for humans in contemporary cultures. This paper explores some of the ...

  • Removal of sulfur compounds from petroleum refinery wastewater through adsorption on modified activated carbon

    The adsorption of sulfur compounds from petroleum refinery wastewater on a chemically modified activated carbon (MAC) was investigated. The modification technique (nitric acid, hydrogen peroxide and thermal modification) enhanced the removal capacity of carbon and therefore decreases cost-effective removal of sulfide from refinery wastewater. Adsorption equilibrium and kinetics data were ...

  • Remediation of refinery waste, oil sludge from lagoons and contaminated soils - case study

    The first VacuDry plant installed at a refinery is designed to treat waste which has accumulated over the last decades, as well as waste that will be generated inside the refinery in the future. The semi-mobile system has a capacity of 1.5 to 2 tons per hour. The plant is designed for maximum flexibility and can treat different types of refinery wastes ranging from dry soil to wet centrifuge ...

  • BP/BTC Pipeline Project

    The Baku-Tbilisi-Ceyhan pipeline is a 1,768 kilometres (1,099 mi) long crude oil pipeline from the Azeri-Chirag-Guneshli oil field in the Caspian Sea to the Mediterranean Sea. It connects Baku, the capital of Azerbaijan; Tbilisi, the capital of Georgia; and Ceyhan, a port on the south-eastern Mediterranean coast of Turkey, hence its name. It is the second longest oil pipeline in the world after ...

  • Restoration of heathland case study

    Dr Phil Putwain has undertaken research over a period of 30 years on the restoration of lowland and upland heathland landscapes following severe disturbance by development projects on uncolonised mineral substrates on marginal farmland. The research findings were applied to practical implementation of heathland restoration on a large scale at sites throughout Britain ranging from the Orkney ...

  • 3D simulation of hydrocarbon–expulsion history: a method and its application

    During the hydrocarbon expulsion simulation process, it is needed to consider the different mechanisms, modes and kinds of expulsion efficiency at different stages, as well as the changes of oil and gas phases, and the solubility of gas in oil and water. Aiming at the above issues, the combination of modelling methods with stages of normal–pressure hydrocarbon–expulsion and over–pressure episodic ...
